In order to access CC, you can head into the TV’s menu, then into the setup sub-menu to access the CC options or to just activate it, press the CC button on the remote control. However, CC is only available via the coax cable since the CC signal has to be sent by your service provider. CC, as far as I know, is not sent via HDMI or other secondary connections from your service providers set top boxes. Captions are subject to your service provider’s availability.
